# LosslessCut
Cross platform GUI tool for lossless trimming / cutting of videos using ffmpeg and electron. Great for rough processing of large video files taken from a video camera, drone, etc. Lets you quickly get rid of the useless parts. It doesn't do any decoding / encoding and is therefore very fast and has no quality loss. Also allows for taking JPEG snapshots of the video at the selected time.
## Download
## Installing / running

- Run app
- If ffmpeg is available in $PATH/%PATH% it will just work
- If not, a dialog will pop up to select ffmpeg executable path.
